Toroidal Flowers (Twisted Polygonal Tori)
This Demonstration explores the shape of a torus with a twisted polygonal cross section . The twisting is achieved by rotating the polygonal cross section around the circular centerline of the torus.[more]
Vary the longitudinal gap to see inside the torus. Change the meridional gap to get different "flower-like" views.[less]
